A method and apparatus are provided for measuring the concentration of contaminants in an aqueous water system, wherein the contaminants are measured with the bioreactor containing a biofilm or microbial community which acts on the water to be analyzed to provide a measure of the amount of the dissolved organic carbon which is biodegradable. A bed for facilitating regulation of water flow through the bioreactor is provided, and an autosampling mechanism enables the measurement of total organic carbon, inorganic carbon and oxygen, between sample inflow and sample outflow at specified time intervals.

[ What is claimed is:] [1.] A measuring device for determining the concentration of biodegradable organic matter in an aqueous environment to be measured, wherein said aqueous environment contains the organisms that form a biofilm, the apparatus comprising:a) pump means for moving a sample of the aqueous environment from a source along a path of travel;b) at least one column having an inlet opening and an outlet opening and a space therein to permit the passage of the sample of the aqueous environment flow through said space, and removable end fittings provided on the column inlet and outlet openings;c) regulating means for facilitating regulation of the sample of aqueous environment flow through a column to provide an even dispersion of a sample of the aqueous environment through the column to equalize residence time between vertical zones of travel through the column, said regulating means including a disk member secured to each end fitting, said disk member having a plurality of apertures therein;d) an outflow line extending from said outlet opening of the column;e) packing material provided within the column space,f) a biofilm within said column, said biofilm being colonized from the aqueous environment, wherein the aqueous environment contains the inoculum that colonizes the biofilm, said inoculum comprising microorganisms of the aerobic aqueous environment.
